You math question answer is going to be d.
The force of friction is given in the scenario:
Force = 500 Newton
and the mass of the runner is 60 kg
To find the acceleration we need to use the relation between force, mass, and the acceleration of the object:

Where 'F' represents the force, 'm' represents the mass, and 'a' represents the acceleration.
Plugging the value of variables we get:

Solving for 'a' (acceleration) we get:
Newton/kilogram or meters/ second squared
So the acceleration of the runner is 8.33 meters/ second squared.

Answer:
this is to hard and I like math
To find the angles in these problems you have to do one of two things.
1) If we are looking for an interior angle with the exterior angle given, we can find the interior angle by subtracting the exterior angle from 180.
EX: Exterior angle K is 140. Therefore the interior angle is 40 (180 - 140 = 40).
2) If order to find an interior angle when you have other interior angles, add up the other interior angles and subtract them from 180.
EX) Interior angle A is 32 because the other angles are 120 and 28. (180 - 120 - 28 = 32)
ALSO, remember that the square is equal to 90 degrees. I've included an answer list for you below.
A = 32
B = 152
C = 65
D = 25
E = 37
F = 83
G = 97
H = 97
I = 83
J = 57
K = 40
L = 120
M = 60
N = 90
O = 79
P = 12
